History of a discovery In 2002, Don Miguel Ruiz was the victim of a heart attack that almost took him away. He spent nine weeks in a coma. The spiritual journey he undertook, while he was suspended between this world and the next, constitutes the heart of this new opus, which is the story of a profound mystical adventure and of a spiritual struggle. While his body lay unconscious, Miguel Ruiz's spirit went to meet the people, ideas and events that formed him, thus giving a light on this fight between life - an energy and an endless truth - and death - matter and subjective knowledge - a fight in which we are all invited to participate. This book is the fruit of 10 years of work. It gives readers access to the mind of a master of the spiritual quest, giving them an intimate and unprecedented glimpse of the evolution of a soul. Ruiz shares with us the intimate functioning of his heart and his mind, encouraging us to confront these eternal revelations, resulting in the very essence of the human life, which is the essence of the very essence of the past.
